Shloka 17
कालनिर्देशः शोकनिवारणं च
Instruction on Kāla and the Removal of Grief
प्रगृह् शस्त्रमायान्तमपि वेदान्तगं रणे | जिघांसन्तं जिघांसीयाजन्न तेन ब्रह्महा भवेत्
pragṛhya śastram āyāntam api vedāntagam raṇe | jighāṃsantaṃ jighāṃsīyāj na tena brahmahā bhavet ||
毗耶娑说：“纵然有一位精通《吠陀》与《吠檀多》的婆罗门，手执兵刃踏入战场，怀杀意而来，也应当奋力将其击杀以自卫。在战斗与自保的情境中如此行事，并不招致婆罗门杀罪（brahmahatyā）。”

Educational Q&A
The verse states that the moral prohibition against harming a Brahmin is not applied in the same way when that Brahmin has taken up arms and is actively attempting to kill in battle; resisting him—even to the point of killing—is treated as a duty of self-defense/warfare and does not constitute brahmahatyā.
Vyāsa lays down a rule for battlefield conduct: if an opponent, even a highly learned Brahmin versed in Veda and Vedānta, approaches with a weapon intending to kill, the warrior should counter him lethally if necessary, without being branded a Brahmin-slayer.
